Colombia's angry top diplomat to America wants President Obama to publicly declare that he's really, really, really sorry for the carnal carnage inflicted on the fine citizens of Cartagena by the Secret Service.

"The U.S. should apologize further," Gabriel Silva told the Colombian newspaper El Tiempo about the sordid sex scandal that involved a dozen agents and another dozen military personnel.

"It is necessary, and I want to hear it from the White House," Silva said in his tough talk to a scribe back home.

Heck, Colombian President Juan Manuel Santos had no beef with Obama when they stood shoulder-to-shoulder at a joint news conference during a summit in Cartagena — the first time the President addressed the unfolding scandal.

"If it turns out that some of the allegations that have been made in the press are confirmed, then, of course, I'll be angry because my attitude with respect to the Secret Service personnel is no different than what I expect out of my delegation that's sitting here," Obama said April 15, two days after the brouhaha came to light.

"We're representing the people of the United States, and when we travel to another country, I expect us to observe the highest standards because we're not just representing ourselves."

Homeland Security Secretary Janet Napolitano condemned the "inexcusable" actions of the rogue agents and noted a thorough investigation is ongoing. Punishment has been swift. Two agents were flat-out fired and six were forced to resign. Another was pushed into retirement and three were cleared of misconduct — they still face internal discipline.

Obama has since deemed the dirty dozen a band of "knuckleheads."

Even the deputy director of the Secret Service sat down with Silva to apologize to Colombia and Cartagena.

Silva is most upset about the portrayal of Cartagena. He's particularly irate over the "superficial, sensationalist" U.S. media coverage that detailed the city's thriving sex tourism industry. "Unfair," he declared.

The ambassador's demand came as the Secret Service acknowledged its investigation into a report that boozed-up agents partied with prostitutes at an El Salvador strip club before President Obama's 2011 visit.

Drunken agents — who, according to hooker Dania Suarez, tried to stiff her on the service fee — bragged during their three-night spree that partying hard and cavorting with hookers was business as usual, according to a stunning report by Seattle's KIRO-TV.

The Secret Service, in a memo sent to Capitol Hill, said it was taking the "allegations of misconduct seriously, and will thoroughly look into this matter," the Daily News learned Thursday.The memo added that the agency has heard no reports of anything similar to the debauchery discovered before Obama's visit this month to Colombia.

The agency has conducted 919 foreign advance trips in the last two years.

"As part of the Secret Service's extensive investigation, it is examining this allegation," said Rep. Peter King (R-L.I.), head of the House Committee on Homeland Security.

"This certainly does not mean that there is any validity to it — just that they are looking into all allegations."
